The topic of this diploma thesis is "Critical success factors of Enterprise Resource Planning Systems in Small and Medium Sized Enterprises" Firstly, the terms enterprise resource planning system, small and medium sized enterprise and critical factor are defined. Part of this thesis is also dedicated to the importance of those systems in small and medium sized enterprises and the supply of products on the market is described as well. The importance of enterprise resource planning systems for this segment of customers is still growing and the number of products offered is quite wide. Customers have unambiguously preferred Czech solutions. Next part of the thesis contains critical factors literature search -- analysis of two studies. Conceptual model of critical factors is made on the basis of findings and comparison of those two studies. The relevance of this model is verified by the analysis of case studies of enterprise resource planning system implementations in small and medium sized enterprises. These case studies were downloaded from websites of system vendors. On the basis of new findings, new model was designed. Each critical factor is described in each part of the thesis to help understand under which circumstances it was used. Finally, the model is assessed.

An assessment has been done and waiting times between production processes have been identified, along with defective products and inefficient work methods. This study proposes the design of a lean manufacturing model under the change management approach, whose methodology comprises five phases. In phase 0, awareness and training sessions are conducted (change management). Then, phase 1 reorganizes the work area (plant layout re-distribution and 5S) and phase 2 seeks better workload balances (line balance and Heijunka implementation). Later, phase 3 standardizes work methods (standardization). Finally, the proposed model will be validated to determine whether the selected operating tools are supported by the awareness that contributes to increasing production. © 2021, Springer Nature Switzerland AG. / Revisión por pares

I dag använder sig verksamheter i alla tänkbara storlekar utav ett eller flera olika affärssystem. Ett vanligt beslut vid anskaffning av ett affärssystem är om det ska vara molnbaserat eller inte. Att affärssystemet är molnbaserat innebär bland annat att en systemleverantör ansvarar för administration och datalagring. Leverantören av molntjänsten hyr ut affärssystemet i form av en tjänst som företaget får åtkomst till via internet. Detta innebär att tillgängligheten till systemet är högre än exempelvis ett lokalt affärssystem. Den tekniska tillgängligheten som möjliggör en hög åtkomst till systemet har konstaterats vara en av de två överlägset största faktorerna till att företag väljer att använda sig av molnbaserade affärssystem. Med denna faktor så tillkommer dock olika risker, som i sin tur visat sig vara den största faktorn till att företag värderar att inte välja ett molnbaserat affärssystem. I denna studie undersöks de risker som kan kopplas till tillgängligheten inom molnbaserade affärssystem. Genom en litteraturstudie och en kvalitativ undersökning lyfter studien fram de olika riskerna som kan uppkomma i samband med tillgängligheten inom molnbaserade affärssystem och hur företag kan arbeta för att motverka dem. Studien resulterar i tre konkreta alternativ för hur företag kan arbeta för att motverka de uppkommande risker. Syftet med studien har varit att bidra till befintlig forskning samt en trygg och hållbar användning av molnbaserade affärssystem för alla företag som använder eller planerar att använda sig av molnbaserade affärssystem. Nyckelord: Affärssystem, Molnbaserade affärssystem, teknisk tillgänglighet, risker, riskhantering / Abstract Today, businesses of all conceivable sizes use one or more different enterprise resource planning systems, also known as ERP. A common decision when purchasing an ERP-system is whether or not it should be cloud-based. The fact that the ERP-system is cloud-based means, among other things, that a system supplier is responsible for the administration and data storage. The cloud service provider rents out the ERP-system as a service that the company can access through the Internet. This means that accessibility to the system is higher than, for example, on-premise ERP-systems The technical accessibility that enables high access to the system has been found to be one of the two by far biggest factors in why companies choose to use cloud-based business systems. However, with this factor however, various risks also arise, which in turn have proven to be the biggest factor in why companies value not choosing a cloud-based business system. This study examines the risks that can be linked to the availability of cloud-based ERPsystems. Through a qualitative study, the study highlights the various risks that may arise in connection with accessibility in cloud-based ERP-systems, and how companies can work to counteract them. The study results in three concrete options for how companies can work to counteract these risks. The purpose of the study has been to contribute to existing research as well as a safe and sustainable use of cloud-based ERP-systems for all companies that use or plan to use cloud-based ERP-systems. Keywords: Enterprise Resource Planning system (ERP), technical availability, cloud-based ERP, risks, risk management

In der Arbeit wird ein Erklärungs- und Gestaltungskonzept für die Wissenskoordination in Projekten zur Einführung und Anpassung von Enterprise Systems (ES-Projekten) entwickelt. Das Modell Lebensfähiger Systeme von Stafford Beer wird zur Verortung, Strukturierung und Gestaltung von Lern- bzw. Wissenseinheiten im Diskursbereich ‚ES-Projekte’ angewendet. Es wird ein Vorschlag unterbreitet, wie ein Enterprise System und ein entsprechendes ES-Projekt auf die Lebensfähigkeit begründenden Systemstrukturen eines Anwendungsunternehmens auszurichten ist. Es wird zudem ein Vorschlag unterbreitet, wie der entsprechende Prozess des integrierten Lernens und Veränderns eines lebensfähigkeitsorientierten ES-Projektes durch ein Software-Tool unterstützt werden kann. / The thesis presents an explanation and design concept for the knowledge co-ordination process in Enterprise System Projects. The Viable System Model of Stafford Beer is used for the detection, structuring and organization of learning and knowledge units within complex Enterprise System Projects. A proposal is made, as to how Enterprise Systems and appropriate Enterprise System Projects are to be aligned to viable system structures of a company. Furthermore a proposal is made, as to how the appropriate process of integrated learning and change in viability-oriented Enterprise System Projects can be supported by a Software-Tool.

Growing enterprises have growing amounts of information. Making sure that this information is easily accessible to its employees is not an easy task. For this task Enterprise Resource Planning (ERP) systems come in handy. However, the ERP systems contain lots of information and may be too complex to handle this information or may be too slow in sharing this information within the organisation. This thesis introduces a new solution for how mobile applications can connect to an ERP system by exploiting database synchronisation, which allows the employees to get the information wherever they are without the need to directly access the ERP system. There are three important questions in this thesis: how the ERP works, how to build a mobile application and, how to build a back end? By combining answers to these questions a whole system is built which is production ready and can copy data between the ERP system and the back end and show the information in a mobile application. The overarching goals were to build a system that could extract data from the ERP system into a proprietary back end and a mobile application that could synchronise with the back end. However, synchronisation between the mobile application and the back end was not implemented due to lack of time. The back end had to be able to scale up to 500 concurrent users and respond within 3 seconds, both of these goals were achieved. The mobile application that was built to display the information to the end user was built with usability in mind, since Netlight wanted a straightforward application that anyone could use. The mobile application was shown to have good usability. The results of this thesis project show that building systems around ERPs, instead of inside them, gives these systems the ability to scale, improved the implementation time, and reduced the company’s maintenance efforts. / Växande företag får mer och mer information. Att kunna se till att den informationen blir enkelt tillgänglig för alla inom företaget är inte nödvändigtvis lätt. Det är ofta det som affärssystem kan användas till, dock innehåller affärssystem väldigt mycket information och kan vara för komplexa för att enkelt kunna hantera information man är intresserad av. Det kan även uppstå problem i prestanda i och med storleken på affärssystemet. I det här examensarbetet föreslås ett nytt sätt för hur mobila applikationer kan integreras med affärssystem genom att synkronisera mot dess databas, vilket tillåter anställda att komma åt informationen vart de än befinner sig. I det här examensarbetet finns det tre olika delar som är intressanta, hur affärssystemet fungerar, hur man bygger en mobilapplikation och hur man bygger ett back end. Genom att kombinera kunskapen från ovan nämnda delar, byggdes systemet som är redo för produktion och kan synkronisera data från affärssystemet till back endet, samt att visa upp informationen i mobilapplikationen. De översiktliga målen var att bygga ett system som kunde extrahera data från affärssystemet till ett eget byggt back end och en mobilapplikation som kunde synkronisera med detta back end. Dock blev synkroniseringen mellan mobilapplikationen och back endet aldrig implementerat. Back endet skulle även kunna skala upp till 500 samtidiga användare och då kunna svara inom 3 sekunder, vilket man lyckades med. Mobilapplikationen som byggdes för att visa information byggdes med användbarhet i tankarna, eftersom Netlight ville ha en enkel mobilapplikation som vem som helst skulle kunna använda. Mobilapplikationen analyserades fram till att vara användarvänlig. Detta examensarbete visar på att det går att bygga system runt affärssystem istället för att bygga dem i affärssystemen, vilket möjliggör att systemet kan skala upp bättre, mindre tid för implementation samt mindre underhåll.
